It depends on your system and your application, and you should measure your system performance (and other metrics) to determine what is best for your particular case. I'm sorry I don't know much about practical ways to go about those measurements. However, 100 to 300 threads is trivial for most modern system. Since most tasks will be IO-bound, it make sense to have lots of threads so some can be running while others wait for data to be returned. (Sorry to contradict Mr. Meier but I'm pretty sure he's off base.) Given a "typical" application I'd probably use 300 threads to start off and measure from there. 3000 is probably approaching some sort of upper limit on most "average" servers. Don't neglect to measure actual running performance, but I don't think commodity hardware can handle that many practically.
